Therefore, it is crucial to determine the underlying cause of your grass discoloration in order to implement the appropriate remedy.
In this blog article, we will delve into the possible reasons why your Zoysia grass is turning brown and explore practical solutions to address each issue. So, let’s roll up our sleeves and bring back the lush green glory to your lawn.
Why is My Zoysia Grass Turning Brown?
If you’ve noticed that your once vibrant green Zoysia grass is starting to turn brown, you may be wondering what could be causing this issue. Brown patches and discoloration in your lawn can be disheartening, especially when you’ve put effort into maintaining a lush, green lawn. In this article, we will explore the various reasons why Zoysia grass may turn brown and provide you with practical solutions to bring your lawn back to its healthy state.
Insufficient Watering
One of the most common reasons for Zoysia grass turning brown is inadequate watering. This grass variety is known for its drought tolerance, but it still requires a proper amount of water to thrive. If you notice brown patches in your lawn, it could be a sign that your grass is not receiving enough water. Factors such as high temperatures, extended periods of drought, or inconsistent watering can lead to dehydration and browning of the grass.
To remedy this issue, it’s crucial to ensure your Zoysia grass receives enough water. Here are some watering tips to revive your brown lawn:
- Water deeply and infrequently: Instead of shallow and frequent watering, aim to water your lawn deeply once or twice a week. This method encourages the roots to grow deeper, making the grass more resilient to drought conditions.
- Water in the morning: Watering your lawn early in the morning allows the grass to absorb moisture before the heat of the day evaporates it. This also helps prevent disease and fungal growth that can occur when the grass remains wet overnight.
- Monitor soil moisture: Regularly check the moisture level of your soil. Stick your finger into the ground to a depth of a few inches. If it feels dry, it’s time to water.
- Consider irrigation systems: If maintaining a regular watering schedule becomes challenging, installing an automatic irrigation system can help ensure your Zoysia grass receives consistent moisture.
Poor Drainage
Another reason for Zoysia grass turning brown is poor drainage in your lawn. When water does not properly drain, it can drown the grass roots, leading to browning and even death. Overwatering, heavy clay soil, compacted soil, or low-lying areas prone to water accumulation can contribute to poor drainage.
To improve drainage and prevent your Zoysia grass from turning brown, consider the following solutions:
- Aerate the soil: Aerating your lawn helps alleviate compacted soil, allowing water to penetrate deeper and roots to grow more efficiently. Use a core or spike aerator to create channels for water and air movement.
- Improve soil composition: If your soil has a high clay content, it can contribute to poor drainage. Incorporate organic matter like compost or sand into the soil to enhance drainage.
- Redirect water flow: If certain areas of your lawn are prone to standing water, consider creating channels or installing French drains to redirect excess water away from the grass.
Incorrect Mowing Practices
Mowing your Zoysia grass incorrectly can also lead to browning. Cutting the grass too short or infrequently can cause stress and weaken the plant, making it more susceptible to browning. Additionally, using a dull mower blade can tear the grass instead of providing a clean cut, leading to brown tips.
To ensure proper mowing practices for your Zoysia grass, follow these guidelines:
- Mow at the appropriate height: Zoysia grass thrives when kept at a moderate height ranging from 1 to 2 inches. Adjust your mower’s cutting height accordingly to prevent scalping or excessive stress on the grass.
- Sharpen your mower blade: Regularly sharpening your mower blade ensures a clean cut, preventing grass damage and browning. A sharp blade also promotes healthy growth and reduces the risk of diseases.
- Follow the one-third rule: Avoid cutting more than one-third of the grass blade at a time. This encourages healthy growth and minimizes stress on the grass, preventing browning.
Disease and Pest Infestation
Disease and pest infestations can also cause Zoysia grass to turn brown. Fungal diseases like brown patch or dollar spot can infiltrate the grass and result in discolored patches. Likewise, insects such as chinch bugs or grubs can damage the grass by feeding on the roots, leading to browning and thinning.
To identify and treat lawn diseases and pest infestations, keep an eye out for the following signs:
- Discolored patches with irregular shapes
- Patches with a distinctive pattern (e.g., circular patterns for diseases like dollar spot)
- Presence of insects or their larvae in the affected areas
If you suspect a disease or pest issue, consider consulting with a professional landscaper or contacting your local cooperative extension office for accurate identification and appropriate treatment options.
In conclusion, if your Zoysia grass is turning brown, it’s essential to identify the underlying cause and take appropriate actions. Whether it’s adjusting your watering practices, improving drainage, adjusting mowing techniques, or addressing disease and pest issues, taking care of your lawn will help restore its vibrant green color. Remember to implement a consistent lawn care routine, and soon you’ll be able to enjoy the beauty of lush, healthy Zoysia grass once again.

Frequently Asked Questions
Why is my zoysia grass turning brown?
There can be several reasons why your zoysia grass is turning brown. Here are some possible explanations:
1. Is my zoysia grass getting enough water?
Insufficient watering can cause your zoysia grass to turn brown. Make sure you are providing the grass with enough water, particularly during hot and dry periods. Aim for deep watering to encourage the roots to grow deeper and become more resilient.
2. Could lack of sunlight be the cause?
Zoysia grass prefers full sun and may become stressed or turn brown if it does not receive enough sunlight. Ensure that your grass is getting at least 6 to 8 hours of direct sunlight per day. Trim any overhanging branches or structures that may be blocking sunlight from reaching the grass.
3. Is my zoysia grass being properly fertilized?
Improper or inadequate fertilization can result in brown patches on zoysia grass. Apply a high-quality, slow-release fertilizer specifically formulated for zoysia grass according to the recommended schedule. Avoid over-fertilization, which can also harm the grass.
4. Could the brown spots be due to pests or disease?
Pests and diseases can cause zoysia grass to turn brown. Common pests include grubs, chinch bugs, and armyworms. Look for signs of pest damage such as chewed grass blades or unusual patterns of brown spots. If necessary, consult with a professional to identify and treat any pest or disease issues.
5. Is my zoysia grass being properly maintained?
Inadequate maintenance practices can lead to brown patches in zoysia grass. Make sure you are mowing at the correct height for zoysia grass (around 1 to 2 inches) and using a sharp mower blade. Avoid cutting more than a third of the grass height at a time, as this can stress the grass and cause browning.
6. Could the brown color be due to dormancy?
Zoysia grass naturally goes dormant and turns brown during colder months or periods of drought. If the browning occurs during these times and the grass is otherwise healthy, it may simply be in a dormant state. Once conditions improve, the grass should begin to green up again.
Final Thoughts
Zoysia grass turning brown can be attributed to several factors. One possible cause is inadequate watering, as zoysia grass requires consistent moisture to thrive. Additionally, improper mowing techniques, such as cutting the grass too short, can stress the plant and lead to browning. Fungal diseases and pests can also contribute to the discoloration. To remedy this issue, ensure that your zoysia grass receives sufficient water, mow at the correct height, and promptly address any signs of disease or pest infestation. By addressing these factors, you can maintain a healthy and vibrant zoysia lawn.
